Upgrade LiveKit Server (v1.8.4-4 -> v1.8.4-5) and integrate with `matrix_metrics_exposure_*`, etc.

Related to https://github.com/spantaleev/matrix-docker-ansible-deploy/issues/4233

This doesn't make Prometheus automatically scrape metrics from LiveKit Server,
nor does it add a Grafana dashboard automatically, etc.

Still, it paves the way for that work being done.
